Optimum Design of TMD System for Tall Buildings

الملخص EN

As tall buildings keep becoming taller, they become more susceptible to dynamic excitations such as wind and seismic excitations.

In this paper, design procedure and some current applications of tuned mass damper (TMD) are discussed.

A symmetrical moment resistance frame (MRF) twenty storey three-dimensional model were modeled in SAP2000 and a TMD was placed on its top and through it to study its effects on the structural response due to seismic excitations and using time history analysis with and without the TMD.

The study indicates that the response of structure such as storey displacements and shear force of columns can be dramatically reduced by using TMD (groups of TMDs) devices especially with a specific arrangement in the model.

The study illustrates the group of four TMDs distributed on the plan (interior) which can be effective as R.C.

core shear wall.
